Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504982, here are decompositions:

  • 31 + 31504951 = 31504982
  • 73 + 31504909 = 31504982
  • 79 + 31504903 = 31504982
  • 109 + 31504873 = 31504982
  • 163 + 31504819 = 31504982
  • 181 + 31504801 = 31504982
  • 199 + 31504783 = 31504982
  • 331 + 31504651 = 31504982

Showing the first eight; more decompositions exist.
